The pins on the motherboard seem to be a lot more fragile, than the pins that are on cpu's such as socket 478 etc, and some of the LGA775 prescotts run really hot no matter what ya do to them. I've had 3 prescotts, a SKT478 2.8@3.5ghz that got up to 63c under load with a thermalright SP-94, a 3.2ghz ES LGA775 @3.6ghz, that runs at 58c with a thermaltake jungle 512, and my horrid 3.4ghz LGA775 prescott that was getting up to 72c with a thermalright XP-120, and throttling. It's now running at 3.91ghz with water cooling, and still gets over 50c under load.
